On the face of it, US President Donald Trump has been dealt a significant blow by America's Supreme Court.
The court today ruled that Mr Trump exceeded his authority in imposing a swathe of tariffs that upended global trade, blocking a key tool the president has wielded to impose his economic agenda.
The judgement has left the White House introducing alternative measures in an attempt to keep its tariffs’ regime in place.
Many governments around the world are holding off from making definitive statements on the judgment.
He said this additional duty would be imposed on top of current tariffs.
When asked about potential refunds following the Supreme Court’s judgment, he said it would have to be "litigated".
He also criticised the court for failing to spell out what its decision means for possible refunds.
EU spokesman on trade Olof Gill said: "We take note of the ruling by the US Supreme Court and are analysing it carefully.
"We remain in close contact with the US administration as we seek clarity on the steps they intend to take in response to this ruling."
The clarity Irish exporters are urgently looking for is whether the EU-US trade deal agreed in Scotland last July will be replaced, or whether there will be 10% tariffs in addition to existing duties as the US president has suggested.
As with everything involving Donald Trump, the full ramifications of what he has announced may not become clear for some time.
In the meantime, exporters to the US face another period of uncertainty.
